dIESELdAN, where did ou get the AL lines. I noticed there are a few sources online like Summit Racing, Aircraft Spruce.... for under $20 for 25 ft. NAPA nor Carquest don't carry the aluminum. Although Carquest sells an alloy tubing by SUR&R.
I need to do my 85D too. Finally got around to looking under the car this morning. Its pretty rusty where most the clamps are. The car conk-out. Wouldn't start. After diagnosis, I have a leak in the supply line as its sucking air and so the engine won't start. Did you change the return line too?

It may have been doable with one solid run for each fuel line but you will really work to get that in my opinion. It just did not look very easy to me at the time. A little short of working room to bend up in there.. Although I was able to fine tune the separate smaller pieces that fit over the axle as required. One other perhaps important item. If you see an area above the axle that looks like the line may rub on later. Just grease the line in that area and slide on a piece of 3/8 inch or other hose for the line. The grease is for future corrosion protection inside the hose. Would not hurt to apply under the fastening clips either for that matter. Depends on how long lasting you want the replacements to endure. In the majority of cases you will replace the brake line as well. Funny enough it is not that bad an issue on the 300d. If you let the master cylinder drain into the new line until you get flow at the rear fitting and tighten it up. I found no bleeding to be required. Pedal was as hard as whern I started. If you manage the one piece for each line in steel without dropping the axle let us know how many new words have entered your vocabulary. Each line installed in two pieces was pretty easy everything considered. Last edited by barry123400; 11-22-2009 at 09:41 PM. |

Does anyone have any evidence as to how Al stands up to salt? Salt is a nasty fact of life in this part of the world, and the old Al. bodied Landrovers did NOT fare well, seems the salt seriously aggravated the dielectrics of having Al in the same general space as the steel frame.
As far as the little bulge to (more or less) duplicate the original, I've had good luck with using the double flare adapter and leaving it at that (don't finish the flare with the cone), plus, it opens up the burr from the cutter without making metal shavings.

I still plan to use aluminum. I spoke with Classic Tube this morning. Apparently, they will bend the tubing for you if you send them the old ones to duplicate. Just another option. Although I will probably do my own. I believe they charge over $100 to prebend. For that, I'll get the bending tool plus the tubing ($20) and be ahead. Here's an interesting article on aluminum corrossion. I believe it states that corrossion on aluminum turns into aluminum oxide which hardens the surface which makes it even more corrossion resistant. http://engineer.cmiwaterfront.com/whitepapers/aluminum_corrosion.pdf

I was underneath the 1985 300D parts car:
FS: parts off of 2 w123s on Sunday........and I'll be happy to remove the fuel lines before it gets crushed.

W126 hard line pump to injector tubing ?
I have a broken hard line from the pump to my #2 injector that needs to be replaced on my 300sdl
if i buy bulk line, what size is it, and does it have to be metric?? just bend it and put a flare on the end correct?? i know a good shop but they only stock american and SAE sizes normally rather than replacing all 6 of them i might just do the one till i get new injectors - then do it right , can't find a source for a new set. Is the dealer the only option or a junkyard unless i bend my own?? Please any help or advice would be greatly appreciated |

Use the Mercedes Hard Line
Either pull one from a ReCycler's or order a New one.
(Phil at the Buy parts tab @ top of page can get it.) Duplicating the Factory OE line's bends successfully is neigh impossible... AND would weaken what's already not as strong as the factory. 'Most important part of the hard lines are the Plastic and Rubber Clamp Buffers that prevent Hard Line Self Destruction by Vibration.

PIctures?
DeiselDan - where are the pics?
I'm just getting around to replacing the lines - very slowly and hopefully, surely. I disconnected the hardline at the tank end from the rubber hoses connected to the tank. All the brackets are disconnected except the one above the rear trailing arm. It appears to have 2 screws instead of just one and the other screw is hard to get to cuz the trailing arm is in the way. I would like to remove the old lines intact so I can copy the bends and attempt to slip it around the arm. There seems to be enough clearance. If not possible I can always cut that portion and run rubber hose. I have both aluminum and steel lines so I'll decide later which one. Can anyone share how they removed the bracket above the trailing arm?

Having read this thread and others I decided to change my lines whilst my subframe, exhaust, propshaft, axles, and the whole lot are still off the car...
I can do some pictures of the car without the lines attached or pictures of the lines removed if anyone wants (Mine's a 1981 W123 300D). With out any obstructions the fuel and brake lines came off very easily - it was 5 min job - they are not bent or distorted so if any measurements are needed I can also supply them. (If I don't respond quickly enough send me a PM and remind me!) |

i would not use rubber hose over the subframe. it may last decades, but then maybe not. also the tool companies make these nifty pliers for clamping the fuel hoses off. you won't need to drain the tank, or wear diesel fuel for the next week.

Thanks!! Glad to know someone actually was able to do it. I got the car jacked up at the driver's side right now with 6 ton jack stands both on front and rear. And i do have aluminum lines. Still have not decided which to use yet.
Right now I'm focusing on removing the old lines intact and try to copy them. I'm like spending 30 min-1 hr each session which about once or 2x a week. at this rate it may take 6 months. Were the brake lines from the dealer prebent?

By popular request!
Here are some pictures as requested.
I hope they are of use - I've just done some general ones at the moment - if you need more drop me a line in the next few weeks from this post (after that time I'm sorry to say they'll be off down the tip). For clarity these have come off of my European 1981 W123 300D. It has no ABS - but I don't know if that makes a difference... The pictures are made as though the car has been turned upside down - imagine the car sitting on its roof and you can look down onto the fuel and brake lines. The three lines are spread apart in an attempt at clarity! |

the brake line was pre-bent, but it was also bent 180deg in the the middle so that it was only half as long to ship. i think you should use the aluminum cause it will be much easier to work with. i can't think of any reason why aluminum would be unacceptable.

Btw, may I ask how much the dealer wanted for the brake line? And when you say it was bent 180 deg, you mean you will need to straighten it out? thanks
